I have tried to connect to the ssh and I get 'This account is currently not available' in the lxadmin control panel and also through Bitvise (xterm closes inmediately).

I opened a ticket some hours ago and got a generic 'I've asked an admin to take a look and will get back to you' message and I'm getting a bit desperate as I really need to run mysqlcheck on a big table which can't be repaired through phpmyadmin.
